877321 ÷ 2 
We want to figure out the number of times 877321 can be divided by 2.

Step 1:
2 goes into 8 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 0 after subtracting 8 from 8.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 2

Let's proceed to step 2:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 6 from 7 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 2

Moving on to step 3:
17 divided by 2 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 438.0
The remainder is 1 after subtracting 16 from 17.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 2

Advancing to step 4:
13 divided by 2 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 4386.0
If we take 12 away from 13, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Going ahead to step 5:
12 divided by 2 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 43866.0
Subtracting 12 from 12 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Going ahead to step 6:
2 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 438660.0
If we take 0 away from 1, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 438660.5
Deduct 10 from 10 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 438660.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 438660.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 438660.5 with a balance of 0.0.
